How to learn automobile sheet metal repair technology?

It takes about 3-6 months to learn automotive sheet metal painting, and you should be able to pass the basic operation. Car sheet metal painting is easy to learn, because there are not too many requirements, as long as you are attentive and interested, you can learn. It is not difficult to learn automobile maintenance technology, but if you want to learn it well, you must spend a lot of time practicing, accumulate more experience, and practice makes perfect before you can become a teacher.

Sheet metal painting is two types of work, sheet metal worker and painter. When the automobile sheet metal is painted, it is first processed by the sheet metal worker, and then handed over to the painter to spray the paint. Sheet metal workers need to learn the use of basic equipment, such as grinding, dismantling, drawing, etc.

Painters need to learn how to spray and dry masking, putty, and various paints.

The basic process of sheet metal painting is usually divided into five steps:

1. Confirm the plan: formulate the corresponding maintenance plan according to the severity of the vehicle collision. If it is a serious traffic accident, it will also involve the engine, gearbox, circuit, etc., and then it will need to be disassembled and repaired by the personnel of the machine repair department.

2. Sheet metal correction sheet metal correction needs to repair the deformed parts through corresponding maintenance equipment according to the degree of deformation of the body. Sheet metal includes cutting, grinding, stretching, receiving, oxygen regeneration, etc., the purpose of which is to restore the deformed parts to their original shape and maintain the original rigidity of the metal.

3. Scraping and shaping: There will be a lot of flaws and repair traces after the vehicle passes the sheet metal, which is an irreparable defect in the sheet metal work, even if the new parts are directly replaced, there will be imperfections, and then it is necessary to reshape the body waist line and flatness by scraping the ash. This process may seem simple, but it is actually a test of the worker's skill.

4. Spraying paint: The process of spraying paint is also relatively cumbersome, and there are also high requirements for the working environment, which needs to be carried out under dust-free conditions. Painting is mainly divided into the following steps:

Spraying the primer - spraying the primer - sanding the primer - mixing the paint - spraying the topcoat - drying the paint.

5. Paint treatment: Paint treatment is the last process in the whole sheet metal painting work. In fact, no matter how meticulous the work of the workers is, there will be some imperfections left behind, even some dust floating in the air will affect the whole effect, and then it can only be remedied by this link.

Usually the main remedy is to use very fine beauty sandpaper or sand with a polisher to achieve a "mirror" effect.

Choosing a good brand of auto repair school is an important factor in choosing a school, and the brand is a symbol of quality, representing the comprehensive strength and quality of the auto repair school. Generally speaking, the teaching quality of auto repair vocational schools with excellent brands is relatively high.

1.Learning technology can be considered from your own interests first.

If you have a skill, then develop what you are good at, so that you can get started quickly, and the corresponding salary will be a little better. Of course, if you don't have a particularly obvious skill or strength, then develop the skill first.

2.First of all, think about your hobbies, what type of work you like to do, and what skills are required for that job, and then learn and cultivate.

3.Considering the development trend in the next few years or 5 years, we will explore hot industries or new industries, and there will be a shortage of talents in hot industries and new industries in the next few years.

4.Field trips, a detailed understanding of the school's training equipment, training situation, teaching content, campus environment and other aspects of the campus before making a choice.

Learning technology is mainly to get started to operate, a semester after the practice of the car can not touch how to learn, but also depends on the proportion of training normal class time. Third, look at the quality of teachers, the level of teachers will greatly make you avoid detours. Fourth, look at the service, a good school has employment services, you graduate, the school will recommend employment.

Automobile sheet metal is equal to automobile sheet metal repair, which is the repair of the car body after the collision, which is called contact welding repair and secondary manufacturing assembly.

The repair of a collision vehicle is not just a knock, the effect of the repair cannot be said to be visible to the eye. There are also special tools and body data to determine the repair of the body, maintenance personnel not only to understand the technical parameters and body size of the body, but also to understand the material characteristics of the body, the deformation trend and the stress point of the body and the body process and welding process, etc. Then only in the case of heating can we restore the original shape, the heating of aluminum and the heating of iron is not the same, the application of aluminum in automobiles has been very wide, only to understand its characteristics and density in order to repair faster and better.

The shape of many sheet metal structures in automobile maintenance is very complex, sheet metal materials must have good plasticity, and must have the ability to be permanently deformed without being destroyed in the case of external force, for cold work parts, there must be good cold plasticity, such as automobile parts stamping parts, for hot work parts, there must be good thermoplasticity, sheet metal parts must have good welding performance, this automobile? Repair is particularly important, the size of the sheet metal is very important to the appearance, only the size and quality of the sheet metal are basically the same as the original factory to ensure that the appearance of the body is basically the same, which is very heavy, which requires superb technology and patience to achieve accurate workmanship.

Yes, the lamp is an assembly, and the fixed position of the mounted lamp may not be correct.

Body dent repair skills: First of all, we must judge the location and size of the car's dent. If the depression area is large, the method of "pulling" can be adopted, and a special suction cup can be used with a "T-shaped device"; If the depression area is relatively small, it is generally necessary to use a special hook to slowly push the depression outward until it recovers; Finally, when the depression is restored, there will generally be some unevenness, which needs to be gently tapped with a rubber hammer until it is completely flat.

The above skills have very high experience requirements for car repairers, if the force is uneven, it is likely to cause secondary damage to the vehicle, so it is very important to find a professional body dent repair shop, which can help you save a lot of costs.
